I just have tried to run phenix.refine after designating the NCS groups,
and it actually worked as I expected. So only is the display not correct
(all chains are shown in every NCS groups) when I re-open ''Detect NCS
Groups'. Maybe it is a bug?

> 2. Put chain A, B, C in 'Torsion NCS restraint group 1'.
> 3. 'Add group' and put chain D, E, F in 'Torsion NCS restraint group 2'.
> 4. Click 'Update and exit'.
> However, after that, when I re-open 'Utilities' -> 'Detect NCS Groups', I
> found all six chains A-F are in group 1, and all six chains A-F in group 2.

> Thank you!
